Mahseer is the common name used for the genera TorNeolissochilus, and Naziritor in the family Cyprinidae (carps). The name Mahseer is however more often restricted to members of the genus Tor. The range of this fish is from MalaysiaIndonesia, across southern Asia to Pakistan, including the Indian Peninsula. They are commercially important game fish, as well as highly esteemed food fish. Mahseer fetch high market price, and are potential candidate species for aquaculture. Several of the larger species have suffered severe declines, and are now considered threatened due to pollutionhabitat loss and overfishing.

The taxonomy of the mahseers is confusing due to the morphological variations they exhibit. In developing strategies for aquaculture and propagation assisted rehabilitation of mahseer species, there is a need to resolve taxonomic ambiguities.

Mahseers inhabit both rivers and lakes, ascending to rapid streams with rocky bottoms for breeding. Like other types of carps, they are omnivorous, eating not only algaecrustaceans, insectsfrogs, and other fish, but also fruits that fall from trees overhead.

The first species from this group were scientifically described by Francis Buchanan-Hamilton in 1822, and first mentioned as an angling challenge by the Oriental Sporting Magazine in 1833, soon becoming a favorite quarry of British anglers living in India. The golden mahseer has been known to reach 2.75 m (9 ft) in length and 54 kg (118 lb) in weight, although specimens of this size are rarely seen nowadays. In addition to being caught for sport, mahseer are also part of commercial fishing and ornamental or aquarium fish.


Catla catla, (Synonymous with Cyprinus catlaGibelion catla), also known as Indian Carp, is the only member of the genus Catla, of the carp family Cyprinidae. It is a fish with a large protruding lower jaw. It is commonly found in rivers and freshwater lakes in IndiaNepalMyanmar, Bangladesh and Pakistan. In India it is commonly known as the Bhakur.



The dwarf gouramiTrichogaster lalius (formerly known as Colisa lalia), has an almost translucent blue color, with vertical red to dark orange stripes. In its native range it is dried for food and it is also kept as an aquarium fish. It has become highly popular for aquaria.

Dwarf gouramis from Singapore may carry dwarf gourami iridovirus. Recent research has shown that 22% of Singapore Trichogaster lalius carry this virus.


The rainbow trout (Oncorhynchus mykiss) is a species of salmonid native to tributaries of the Pacific Ocean in Asia and North America. The steelhead is a sea-run rainbow trout (anadromous) usually returning to freshwater to spawn after two to three years at sea; rainbow trout and steelhead trout are the same species. The fish are often called salmon trout. Several other fish in the salmonid family are called trout, some are anadromous like salmon, whereas others are resident in freshwater only.

The species has been introduced for food or sport to at least 45 countries, and every continent except Antarctica. In some locations, such as Southern EuropeAustralia and South America, they have negatively impacted upland native fish species, either by eating them, outcompeting them, transmitting contagious diseases, (such as whirling disease transmitted by Tubifex) or hybridization with closely related species and subspecies that are native to western North America.
